that is the materials that came out of osama bin laden's home in pakistan. there is evidence as late as february 2010 bin laden wanted strikes in the u.s., particularly around symbolic holidays. are you more concerned than you usually would be about this weekend or are you feeling reasonably steady that this looks like a weekend that we are well prepared for? >> i would almost say all of the above. i do feel reasonably secure because we have increased security as far as alerting local governments, alerting the private sector. there is no doubt we do know al qaeda was talking more about attacking the u.s. on symbolic dates. also in the lead up to 9/11, the tenth anniversary of september 11th, we know they are considering, trying to plan attacks. having said that, i'm not aware of any particular attack being planned right now. we do know they are looking for symbolism. they want to do something dramatic before september 11th. obviously, fourth of july would be a prime time for that. everyone has been alerted to be on extra guard, to be much more careful. becau
